We take safety very seriously. Our masks are third-party tested to meet the U.S. Consumer Protection Safety Improvement Act (CPSIA) requirements. Our masks and mask straps are certified to meet the CPSIA requirements for durability, small parts, and chemicals. Our masks are made with two layers of fabric. Our ear straps are sewn with a special "butterfly" closure at the end that helps prevent the bead adjuster from falling off the end. That being said, our masks are not suitable for children under 3 years old and our mask lanyards are not suitable for kids under 4 years old.
